fi m, -i lm ay con ccm known that I. JosnrirSrMoN, a subject of theKingot Great Britain, residing at' Halifax, Province ofNova Scotia,Canada,

have invented certain new and useful lmprovemeits in AntiskiddingAttachments for ire Chains; and l do herebydeclare that provision of atire chain such as above refer-red to, which has novel anti-shieldingattachments arranged to grip the roadway to prevent the machine to whichthey are applied fromv slipping or skidding.

Another object of the invention is the provision of a device such asabove referred to which will insure adequate gripping surfaces to allowthe car to pull up slippery hills and the like or over snow and icecovered roads.

The invention as a further and more specitic object contemplate theprovision of a device ofthe above c aracter embodying briefly supportingbase having integral side flanges shaped to form main and secondarycleats and carrying reinforcing members shaped to form seats for theretaining means for the ianges, A stillifurther obj ect oi' theinvention is the provision ot a tire chain 'for automobiles and thelike, and in particular to tread attachments for the chain Which will becomparatively simple and inexpensive to manufacture, reliable andefficient in use, and readily operated. 1

`With the above and other objects in view, the present invention residesin the novell features of construction, formations, combi,- nations, andarrangements of' parts to hereinafter more fully described, claimed andillustrated 'in lthe accompanying drawing forming a part of the presentapplication; and in which,

Figure 1 is a side vien7 of the tire chain applied to the ,Wheel of anautomobile or the like;

Figure 2 is a perspective vieur of a portion ot the chain with one ofthe tread members Y applied thereto; and,

Referring now to the accompanying draW- ing by corresponding charactersot reference throughout the several views, the numeral 5 designates ingeneral the rim' of an automobile Wheel or the like which carries theusual tire 6.

My improved chain is shown at Tand comprises a pair of side members 8connected at their ends by suitable clamps 9 and support ing the treadmembers 10. These tread members 10 are of improved construction and eachcomprises a curved base 11, of substantially rigid sheet metal, havingintegral side flanges 12, the straight outer edges of which form maincleats 13 for engagement With the road to prevent the Wheels fromslipping,

While thefouter corners are pointed and bent slightly inwardly formingsecondary cleats 13 for engagement with road or ground to the side ofthat engaged by the main cleats.

The basel1=is curved to conform to the curvature of the tire 6, Whilethe side flanges 412 at their ends are connected by rods 14 which holdthem in their proper spaced relation and prevent them from bending outof shape when in use. Reiniorcing angle members 15 of strap metal arenow employed'and have their outer portions secured by Jfasteners 16 tothe base adjacent the central portion thereof, being previously bent attheir points of distortion to form seats for the rods 14, While theopposite portions are secured by rivets adjacent the free ends of thebase 11 which latter has also been previously bent to form loops 18 forreceiving hoolrs 19 which attach the tread members 10 to the links ofthe side members 8.l

Any number of tread members 10 may be `employed as desired, and itwvillbe readily .5seen that when positioned in the manner shown in Figure 1upon the Wheel of an automobile or the like they will prevent the saidWheel from slipping or skidding. It is believed in View ofthe foregointhat a further detailed description is entire y unnecessary.A lt may beadded however, that stress-is laid on the arrangement of the rein- Yforcing members for both the base and its flanges, as Well as theprovision of the seats therein for the flange retaining bolts', thisfeature assuring rigidity and consequent durability.

From the foregoing description taken in i l. lconnection With theaccompanyingdrawing, `Ait will be manifest tirata tire cham is providedwhich Will fulfil all ofthe neeyy requirements of such a device, and itshould be understood in .this connection that various minor changes inthe specific details of construction can be resorted to within the scopeof the appended claims Without departing from the spirit or sacrificingany of the advantages of the invention.

Having thus fully described .the invention what claim as nevvr anddesire to protect by Letters Patent is:

1. ln a device of the character described, an arcuate supporting base,integral flanges thereon, reinforcing angle members carried by the baseand formed with seats, `and fastening members arranged in the seats andengaged in the ianges for retaining the anges against the reinforcingmembers.

2. 1n a device of the character described, an arcuate supportingandattaching base, a pair of iianges integral With the'opposite -edgesofthe central portion of the base and shaped to form main and secondarycleats, reinforcing angle members secured to the outer surface andopposite sides of the base and contacted by the flanges and also formedwith seats, and retaining rods arranged in the seats and engaged throughthe ianges for maintaining the flanges in contact with the edges of thereinforcing members.

3. 1n a device of the character described, an arcuate tire engaging andsupporting base having attaching loops at its terminais, op posed sideflanges integral with the main pon tion of the baseprovidedwith straightouter edges to form main cleats and having their outer corners pointedand turned slightly inwardly to form secondary cleats, reinforcing anglemembers secured to the enter surface and opposite sides of the base andbent at their points of distortion to form seats, and

- retainlng members arranged in the seats and engaged With the langesfor maintaining the Hanges against the side edges of the reinforcingmembers.

n Witness whereof i have hereunto set my hand.
